IMPROVEMENT IN OlLERS'.

Specification forming part of Letters Patent No. 172, [61, dated January 11, 1876; application filed December 18, 1875.

To all whom it may concern:

Be it known that I, GEORGE W. PARSONS, of Salisbury, in the county of Wicomico and State of Maryland, have invented a new and useful Improvement in Oilers, of which the following is a specification:

Figure 1 is a side View, partly in section, of an oiler to which my improvement has been applied. Fig. 2 is a detail view of the gearing for operating the valve. Fig. 3 represents a modified form of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved oiler, which shall be so constructed that it may be overturned without spilling any of the oil, and which will enable the amount of oil discharged to be readily controlled.

The invention consists in the combination of the rack-valve wire, the gear-wheel or gear-segment, the rack-wire, the spring, and the frame with the body and nozzle of an oiler, and in the combination of the catch with the rack-valve wire, the frame, and the spring, as hereinafter fully described.

A is the body or cup of the oiler, which is made with a spring-bottom, and into the neck of which is screwed the nozzle B, in the usual way. 0 is a wire, which passes in through the cavity of the nozzle B, and is provided with a valve, 0, to close the said "cavity. The lower end of the wire 0 passes into the body A along a bar of a frame, D, attached to the base of the nozzle B. Upon the inner side of the lower end of the wire 0 are formed teeth 0 which mesh into the teeth of a small gearwheel, E, pivoted to the frame D. Along the other side bar of the frame 1) passes a wire, F, which has teeth d formed upon the side of its upper part, that mesh into the teeth of the gear-wheel E. The lower end of the rack-wire F extends nearly to the bottom of the cup A,

as shown in Fig. 1. By this construction, when the spring-bottom of the oiler A is .pressed inward, the rack-wire F will be forced raised from its seat, to allow less or more oil to escape, by pressing the projecting end of the wire (3 against the surface to be oiled with less or more force, according as less or more oil is required. The valve 0 is raised to its seat, and is held in said seat, by a spiral spring, G, coiled around the lower part of the wire 0. The lower end of the spring G rests against the frame D, and its upper end rests against a pin or collar attached to the said wire 0. To the lower end of the frame D is attached a spring-catch, H, which, when the wire 0 is fully forced in, catches upon the teeth of the said wire 0, and holds it, allowing the oil to flow out freely. The catch H may be detached from the wire 0 by giving the oiler a sudden jar. If desired, the gearwheel E may be made in the form of segments of gear-wheels, as shown in Fig. 3.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of the rack-valve wire 0 0 0 the gear-wheel or gear-segment E, the rack-wire F, the spring G, and the frame D with the body A and nozzle B of an oiler, substantially as herein shown and described.

2. The combination of the catch H with the rack-valve wire 0, the frame D, and the spring G, substantially as herein shown and described.

GEO. W. PARSONS.
